Tempest

A goddess and a demon prince made peace once, and got three impossible children out of it. Centuries later those kids are walking around as vessels for something neither heaven nor hell can control, and an exiled Sentinel Angel is stuck babysitting alongside a demon and a fallen angel who used to be on the other side of this fight.

The premise leans hard into the idea that this isn't good against evil, it's a custody dispute over free will, with three human lives as the paradox at the center. That framing carries the story more than any single set piece does.

Play is visual novel branching: you follow the Sentinel's choices as he and his mismatched allies decide how to protect the three, with the Southern Forest arc singled out as a point where exploration choices actually change what scenes follow. The current general release covers the main story through Chapter 3 without the explicit material, which is being held back for a separate, more adult cut of that chapter.
